Testing servo motor with arduino

 Testing servo motor with arduino 

Components Needed:

1. Arduino board (e.g., Arduino Uno)

2. Servo motor

3. Jumper wires

Steps for Connection:

1. Servo Motor Pins:

• Ground (GND): Usually the brown or black wire of the servo motor.

• Power (VCC): Usually the red wire of the servo motor.

• Control Signal (PWM): Usually the yellow, orange, or white wire of the servo motor.

2. Connecting to Arduino:

• Ground (GND): Connect the ground wire of the servo motor to one of the GND pins on the Arduino.

• Power (VCC): Connect the power wire of the servo motor to the 5V pin on the Arduino.

• Control Signal (PWM): Connect the control signal wire of the servo motor to digital pin 9 on the Arduino, as specified in the code by myservo.attach(9);

Connection

Arduino	Servo motor
VCC/ 5V	Red wire
GND	Black Wire
9	Yellow wire

Explanation:

• Ground (GND): This connection ensures that the servo motor and the Arduino share a common ground, which is necessary for proper operation.

• Power (VCC): The servo motor needs a power supply to operate. The 5V pin on the Arduino provides a suitable voltage for most standard hobby servo motors.

• Control Signal (PWM): The control signal wire is connected to digital pin 9 on the Arduino. This pin will send PWM (Pulse Width Modulation) signals to the servo motor to control its position. The myservo.attach(9); function in the code specifies that pin 9 is used for this purpose.

This setup allows the Arduino to control the position of the servo motor by sending PWM signals through pin 9, as demonstrated in the loop() function of the provided code.

Circuit Diagram 

Arduino Code 

#include <Servo.h>  // Include the Servo library which allows us to control servo motors

Servo myservo;  // Create a Servo object named myservo to control a servo motor

void setup() {

  myservo.attach(9); // Attach the servo motor to pin 9 of the Arduino

}

void loop() {

  myservo.write(0);  // Set the servo position to 0 degrees

  delay(1000);       // Wait for 1000 milliseconds (1 second)

  

  myservo.write(90); // Set the servo position to 90 degrees

  delay(1000);       // Wait for 1000 milliseconds (1 second)

}
